In urging men not to masturbate, Pastor
Mark Driscoll argues it's a form of homosexuality.

In
a booklet titled Porn-Again Christian: A Frank Discussion on
Pornography & Masturbation for God's Men, Driscoll of the
Seattle-based Mars Hill Church suggests that the act could turn men
gay.

“First, masturbation can be a form of
homosexuality because it is a sexual act that does not involve a
woman. If a man were to masturbate while engaged in other forms of
sexual intimacy with his wife then he would not be doing so in a
homosexual way. However, any man who does so without his wife in the
room is bordering on homosexual activity, particularly if he's
watching himself in a mirror and being turned on by his own male
body.”

In sermons offered at this website,
Driscoll also says that Christians should judge gay people like
Jesus.

“If you leave this church, you can go
to another church and they will tell you if you are living together
and not married, that's okay. They'll tell you if you're gay, that's
okay. They'll tell you if you're married and you're into porno and
wife-swapping and open marriages, that's okay.”

“God is displeased with that conduct.
…. Christians therefore must be judgmental like Jesus,” he adds,
quoting the Apostle Paul.
